To @ZZ whom t may concern.-

Be it known that we, WILLIAM .I-I. ARNER, residing at Groveland, in the county of Livingston, and EDWARD L. HENDERsIIoTT, residing at Penfield, in the county of Monroe, State of New York, citizens of the United States, have invented certain new and useful Improvements in Milk-Cans; and We do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in mi1k-cans, and more particularly to that class of delivery-cans used for retailing milkto consumers; and the object is to provide a can of this kind for conveniently straining and measuring the milk and registering the same. p To this end the novelty consists in the construction, combination, and arrangement of the same, as will be hereinafter more fully described, and particularly pointed out in the claims.

In the accompanying drawings the same reference characters indicate the same parts of the invention.

Figure 1 is a side elevation of a delivery-can embodying our invention. Fig. 2 is a vertical section of the same. Fig. V3 is a plan view of the removable cap with theftop plate removed. Fig. 4 shows the canin position forreceiving its supply of milk. Fig. 5 "is a planvew of the registering-dials. Fig. 6 is an enlarged section of the registering mechanism. Fig.`7 is a plan view of the operating knob or handle, showing theorifice through which the registering-dials are read, and thedetached view at" the top of said figureI shows the baycnet-catch for locking the sleeve. Fig. Sis a plan vieW'O'rfthestrainer-fraine. Fig. 9 is a detail section `of the sleeve 25.

1 represents the milk-can, which may be of any size or capacity. It is provided with a anged neck 2 and a horizontal bottom 3, provided with a concave recess 4. The lower end of the can is provided Witha reinforcing-band 5, provided with orifices 6 6, which receive the pins 7 7 on the spring-arms 8 8, fixed tothe false bottom 9. I

10 represents ia heating-lamp Xed to .the bottom 9, and its Wick-tube 11' is provided with a deflector-plate 12, located above the ame to diffuse the heat over the bottom 3 to prevent the contents of the can freezing in cold Weather. .The wick-tube 11 is provided y with a draft-shield 13, and 14 represents a raised top which encompasses the upper end of the lamp, under which the air passes to the shield and burner,,the air being .admitted to the lamp through the orifice a in the annular flange b of the false bottom 9.Y '15 represents a removable cap whichsnugly fits the neck 2 of the can, and it is provided with an air-vent 16, through which air is admitted to supply the space occasioned by withdrawing the contents of the can. This airvent 16 extends upwardly inside of the neck of the can and level with its mouth.

17 represents a cylinder open at its upper end Aand closed at its lower end, and said cylinder is removably secured in the cap 15 by means of .the set-screws 19, passing through the slotted lugs 20, fixed on the upper end of thecylinder.

21 represents the piston, snugly fitting the cylinder 17, and its lower edge is provided with a rubber or other elastic packing-ring 22, which projects into an annular recess 23, formed in the bottom 18 of the cylinder when the piston is at the lower end oflits stroke.

24 represents a central cylindrical stud on the piston' 21, and it is externally threaded to receive the internally-threaded end of the tubular piston-sleeve 2,5,which projects through the upper endof the cap. This tubular piston-sleeve is I formed with a vertical keyway 26, which receives the key 27 .ofa `hub 28, which encompasses said sleeve'. This hub is journaled'fin the upper end of the cap by means of the flanged `lugs 29,'and it is also provided with an arm 30, to the outer end of which is pivoted a connecting-rod 31, which inturn ispivoted `to the outer end of a shorter arm 32"by ahollowpivot332, through Which the stud-bolt 32 enters.y The opposite end of said shorter arm 32 is pivoted to the under face of the cap 15 by the pivot-bolt 35, and the lower face of this end of said shorterV arm is formed With a square socket 36 to receive the correspondingly-shaped,centerpint on `the upper face of the pivoted'spout 33, and

35 represents a'small. elliptical 4springwhich IOS fits over the shoulder of said center pin 34 and rests against the upper face of the pivotbolt 35 to impart the proper tension to the spout and hold it in place.

The lower edge of the spout 33 is formed with a flanged bearing 37, which snugly fits a corresponding female flange 3S in the lateral extension-pipe 39, formed in the bottom of the cylinder 17.

A foot-valve 40 is hinged to a circular plate 40', which rests on a rubber packing-ring in the flange 38, and the flange 37 of the spout rests upon this plate to form an air-tight joint at this point and at the same time form abearing for the spoutto turn on. This foot-valve 40 is provided with a curved arm 4l, which projects into the path of a depending arm 42, fixed on the lower face of the piston 21, so that when the piston is at the bottom of its stroke the dependingarm42 strikes the curved arm 41 and raises the valve to allow the liquid to drain back into the can.

43 represents a vertical cylindrical tube communicating at its upper end with the branch pipe 39, connecting the spout and cylinder, and its lower end extends downwardly and terminates in the recess 4 in the bottom 3.

39 represents a screw-threaded cap removably secured to the correspondingly-threaded lower end of the tube 43, and 44/ represents a disk plate removably secured with a suitable packing between the lower end of said tube and the cap 39', and it is provided with a foot-valve 44, and it will be seen that when a vertical movement is imparted to the piston the contents of the can will be forced upwardly through the tube 43 and discharged through the spout 33.

The capacity of the cylinder 17 is equivalent to', say, a pint. Therefore each upward movement of the piston will draw a pint of milk from the can and run through the tube 43 into the cylinder 17, and on the downward movement of the piston this pint or other given quantity will be discharged through the spout 33.

45 represents a central vertical stud on the upper end of the pistonsleeve 25, and on this stud is journaled a large register-disk 46 and a smaller corresponding disk 47. The upper faces of these disks are provided with divisionspaces 48, which indicate the number of times the piston has been reciprocated. The periphery of the registering-disk 46 is provided with projecting teeth 49, which correspond to the divisions on the disk.

50 represents a curved spring fixed on the top of the sleeve, and its free end terminates in a notched pawl`5l, which projects into the path of the teeth 49 to retain the disk in po- Sition.

The disk 47 is provided with a series of teeth 52 on its under side corresponding to the number of divisions on its face.

53 represents a curved spring fixed to the under side of the disk 46, and its vertical free end 54 projects through a slot in said disk,

and it is adapted to be projected into the path of the teeth 52 on the disk 47 when its free end rides over a lug 55, so that one complete revolution of the larger disk 46 will move the smaller disk one tooth.

A vertical rod 56 is mounted in the guide,- lugs 57 57, and it is provided with a spiral spring 53, its upper angular end 59 projecting into the path of the teeth on the disk 46 and its lower end into the path of the stationary lug 60, fixed on the cap 15, so that when the knob 61 is turned to swing the spout 33 outwardly and the knob then pressed down the rod 56 comes in contact with the lug 60, which moves the disk 46 one tooth, which may be read through the visual orifice 62.

63 represents a lateral slot in the sleeve 25, extending horizontally from the upper end of the keyway 26 and which will engage the key 27 in the hub 23 to retain the knob in the position shown in Fig. 2 when the spout 33 is closed in the can.

64 represents a spiral spring encompassing the sleeve 25 and having its lower end 65 bent downwardly at a right angle to engage an orifice 66 in the top plate of the cap 15, and its upper end engages the corresponding oriice 67 in the knob 61, and the ofce of this spring is twofold, its tension being exerted in one direction to restore the spout to its normal position in the cap when not in use and also to raise the knob, sleeve, and piston after it has been pressed down by hand. Ahorizontal orifice 63 in the wall of the cap 15 is closed by a curved door 69, hinged on a vertical shaft 70 in the cap 15, and its inner end is provided with an angular arm 71, which projects into the path of the outer end of the spout 33, which comes in contact with and automatically closes said door when the spout is withdrawn into the can.

72 represents a pawl-spring which encompasses the post 73, and its larger end rests against the inner wall of the cap, while the other or free end rests against the arm 71, so as to force said door 69 outward when released by the spout.

74 represents a flange extending part way around the neck 2 of the can to receive the strainer-frame 75, which holds the cloth 76 in place in the neck 2 of the can. This strainerframe 75 is provided with a recess 77 to correspond to the air-vent 16 in the neck and with a clamp 7 8, which encompasses tube 43, so that the strainer-cloth 76 is removably secured in place in the neck 2 of the can.

To fill the can, the cap is raised and turned to one side, as shown in Fig. 4. The clamp 78 in the strainerframe supporting the cap in position, the milk is then poured into the mouth of the neck of the can and through the strainer-cloth 76. The cap 15 is then restored to its normal position, and the can is then ready for use or to deliver milk in such quantities as maybe required. To draw milk from the can, the knob 61 is turned slightly to the left to release the slot 63 from the key IOO and when the piston is at the lower end of itsl stroke its arm 42 strikes the curved arm 41 on the valve 40 to raise it and allow the surplus milk in the spout to fall by gravity into the tube 43 and through an orifice 79 in the bottomof the tube to a point corresponding to the level of the milk in the can. After a given quantity of milk has been measured off a reverse motion of the knob restores the delivery-spout within the cap, and the knob be-A ing pressed down is locked in position, as

hereinafter described.

While this can is especially applicable to the handling of milk, it is obvious that it is equally adapted for dispensingother fluids.
